Rubidium has a larger atomic radius than lithium and iodine primarily because it is located further down the Periodic Table, in group 1. As you move down a group, additional electron shells are added, increasing the distance between the nucleus and the outermost electrons. Although iodine is larger than lithium, it has a higher nuclear charge, which draws its electrons closer, resulting in a smaller atomic radius compared to rubidium. Thus, the combination of more electron shells and weaker effective nuclear charge in rubidium leads to its larger atomic radius.
What else can I help you with?
Why does rubidium have a larger radius than silver?
Rubidium has a larger atomic radius than silver primarily due to its position in the periodic table. Rubidium is an alkali metal located in Group 1, while silver is a transition metal in Group 11. Rubidium has fewer protons and electrons, resulting in a weaker effective nuclear charge on its outermost electron, allowing it to be more loosely held and thus increasing its atomic radius. Additionally, rubidium has more electron shells compared to silver, contributing further to its larger size.
Why does tellirium has a larger mass number than iodine?
Iodine is a non metal element. Atomic mass number of it is 127.
Does an atom of fluorine have larger or smaller radius than an atom of iodine?
Smaller
Does tin has a larger atomic size than iodine?
The empirically measured covalent radius of tin is 145 pm; for iodine this radius is 140 pm.
Which one has the larger radius strontium atom or an iodine atom?
Strontium has a larger atomic radius than iodine. This is because strontium is located in Group 2 of the periodic table and is a metal, while iodine is a nonmetal found in Group 17. As you move down the periodic table, the atomic radius increases due to the addition of electron shells, and strontium, being lower in the table, has more electron shells than iodine.
How does electron shielding explain why it is easier to remove an electron from rubidium than from lithium?
In rubidium, having a larger atomic radius, the attraction force between the atomic nucleus and and the electron from outermost shell is lower.
Why does rubidium have a larger atomic radius than sodium?
Rubidium has a larger atomic radius than sodium because rubidium has more electrons and energy levels, leading to increased electron-electron repulsion and a larger atomic size. Additionally, the outermost electron in rubidium is in a higher energy level compared to sodium, contributing to a larger atomic radius.
What element has larger atomic radius than rubidium?
Cesium has a larger atomic radius than rubidium. This is because as you move down a group in the periodic table, the atomic radius generally increases due to the addition of more energy levels and electrons.
Which is bigger the atomic radius of potassium or atomic radius of iodine?
The atomic radius of iodine is larger than the atomic radius of potassium. This is because as you move down a group in the periodic table, atomic size increases due to the addition of more electron shells. Iodine is located below potassium in the periodic table, hence it has a larger atomic radius.
Least reactive to most reactive elements Lithium potassium Rubidium.?
Rubidium is the least reactive, followed by potassium, and then lithium. This trend is due to the increase in reactivity as you move down the alkali metal group on the periodic table, with larger atoms having more easily discarded outer electrons, making them more reactive.
Is rubidium harder or softer than potassium why?
Rubidium is softer than potassium. This is because rubidium has larger atomic size and higher reactivity, which makes it more easily deformable when compared to potassium.
Why does rubidium have a larger radius than silver?
Rubidium has a larger atomic radius than silver primarily due to its position in the periodic table. Rubidium is an alkali metal located in Group 1, while silver is a transition metal in Group 11. Rubidium has fewer protons and electrons, resulting in a weaker effective nuclear charge on its outermost electron, allowing it to be more loosely held and thus increasing its atomic radius. Additionally, rubidium has more electron shells compared to silver, contributing further to its larger size.
Why does tellirium has a larger mass number than iodine?
Iodine is a non metal element. Atomic mass number of it is 127.
Why is the lattice energy of potassium bromide more exothermic than the lattice energy of rubidium iodide?
The lattice energy of potassium bromide is more exothermic than that of rubidium iodide because potassium and bromine have smaller atomic sizes and higher charges, which leads to stronger ionic bonding in potassium bromide. Rubidium and iodine have larger atomic sizes and lower charges, resulting in weaker ionic bonding in rubidium iodide. The stronger ionic bonding in potassium bromide requires more energy to break, resulting in a more exothermic lattice energy.
Does an atom of fluorine have larger or smaller radius than an atom of iodine?
Smaller
Why is rubidium more reactive than sodium?
Rubidium is more reactive than sodium because rubidium has a larger atomic radius and fewer electron shells, making it easier for rubidium to lose an electron and form a positive ion. This tendency to lose an electron increases its reactivity compared to sodium.
Which atom has the larger atomic radius K or Li?
K has a larger atomic radius than Li. This is because atomic radius generally increases down a group in the periodic table, so potassium (K) being below lithium (Li) in Group 1 will have a larger atomic radius.
